I'll do a more in-depth review later, but suffice it to say that the last 2 years of Battlestar Galactica have suffered from rushed plotting and a lack of texture that made the drama so wonderfully realistic in the show's first season. While the conclusion to the series in Season 4.5 might not have been all it promised in terms of further rushed plotting -- mostly due to the Syfy Network not promising the show a 5th season -- this release rectifies those problems for 3 of those episodes, which are given new life here. "A Disquiet Follows My Soul" is over 9 minutes longer, "Islanded in a Stream of Stars" is over 19 minutes longer, and the finale, "Daybreak", is over 11 minutes longer. They are all in far superior form here, especially the first 2 extended episodes, which take on a whole new life, when compared to the aired versions.
My one major complaint that hopefully will be rectified with future releases is that this was not done with more episodes. As reported by other fans, "Deadlock" had a much more elaborate subplot with Baltar that was cruelly cut down; "Blood on the Scales" had 40 minutes cut out of it. All this tends to weaken the drama, as even bits of dialogue are omitted from the aired versions. However, recutting episodes with new music and sound mixing costs quite a bit, so the producers may have wanted to hold off more extended versions for future releases, which we'll hopefully get for not only the remainder episodes of 4.5, but also 4.0 and much of Season 3's action-oriented episodes.
In any case, despite its lesser political exploration, simply not enough story moments for Lee Adama and many lesser characters, and far too much Starbuck, Season 4.5 is still a great and emotionally satisfying conclusion, especially the finale, to the most politically insightful show in the history of American pop culture.
